More speed requires more control and, with
cyclocross, that control is heavily based on the rider’s connection with the
terrain. Working in conjunction with elite athletes, Challenge has developed a
new tubular tire line with improved traction, cornering, casing protection and,
most important, more speed.

Changes to the new Team Edition “S” tire line include these three key features:

Softer: a proprietary softer
compound rubber in the tread improves traction providing more grip on climbs and
descents while increasing confidence in corners.

Suppler: this new softer compound
allows Challenge to tune the tread’s base rubber to both reduce weight and
further improve tread flexibility. Combined with 320TPI Corespun Cotton casing
and a seamless latex inner tube, the whole tire deforms to create the largest
tire patch possible, absorbing every trail imperfection, maximizing traction and
eliminating bounce to minimize rolling resistance.

Sealed: also included is a
special, latex formulated, tread-to-base tape sidewall coating that is applied
in a thin coat that improves casing flexibility, prevents water absorption and
maintains a brighter appearance.

The new tires include all the above changes with
no sacrifice in durability. The factory-applied sealant binds and seals each
cotton thread to keep the entire casing clean and dry, maintaining the lightest
weight; a shiny white appearance; improving UV protection; saving you time and
money hand-treating the sidewalls with a messy, unhealthy, solvent-based sealant
and providing you the longest possible tire life – protecting your investment.

All these improvements make the tire fast in every condition giving the rider
confidence to push to their limit. Just ask these athletes:

“I rode Worlds with the Team Edition Grifo. Where everyone else had to ride mud
tires, the Grifo gave me an excellent amount of grip in the corners due to the
perfect balance of sidewall agility and the rubber tire tread. With the Grifo I
had an advantage on the road sections. The new Team Edition S are better for
handling with low tire pressure and more speed!” - Eli Iserbyt, Telenet Fidea, U23 Cyclocross World Champion

“Over the past seasons I’ve been working with Challenge to get the perfect
balance of soft and supple rubber with the new casing on the Team Edition
tubulars. I’m confident we’ve done this and the additional grip is noticeable in
the corners. I know that gives me more confidence to push my bike to the
limit.” - Helen Wyman, Kona, 9X National & 2X European Cyclocross Champion

“I found the new soft compound tires gave me more grip in the corner with no
reduction in straight line speed.” - Ellen Van Loy, Telenet Fidea, 4th
Overall Elite Women’s Cyclocross World Cup

“No matter how you prepare or how good you feel, if you aren't on the right
equipment it makes it very difficult to stay with or even ahead of the game.
Having the softer tire and more supple compound means traction and smooth
rolling without compromise. Low pressure without folding over is key to be able
to roll fast and stay with the best riders in the race. I get that confidence
with the Team Edition tires.” - Stephen Hyde, Cannondale p/b CyclocrossWorld.com, 2nd
2016 US Elite National Cyclocross Championships
